NEMIX RAM 48GB DDR5 4800 CL40 2Rx8 1.1V ECC Registered RDIMM Supermicro H13SSH memory upgrade

48GB DDR5 ECC RDIMM for Supermicro H13SSH

This 48GB DDR5 4800 Registered ECC module is built for the Supermicro H13SSH motherboard. It uses the 288-pin RDIMM form factor and 2Rx8 organisation that the board's memory controller expects. The exact voltage, rank structure and timing let the system recognise full capacity at rated speed without manual tuning. It is not for platforms that require unbuffered UDIMMs or SODIMM modules.

Thermals and power draw

Operating at 1.10V standard DDR5 voltage, the module draws minimal power per slot and runs without a heat spreader. Registered buffering reduces electrical load on the memory controller, helping stability when every slot is populated. No active cooling is required under normal server airflow. Fan noise and thermal output remain dictated by the chassis design, not the memory itself.

Registered ECC with 2Rx8 organisation

The single specification that decides fitment is the Registered ECC 2Rx8 architecture at CL40. This combination matches the H13SSH memory population rules so the board can run fully populated at 4800 MT/s. Boards that only accept unbuffered non-ECC UDIMMs or different rank configurations will not support this module. Verify your manual for approved DIMM order and maximum capacity per slot before purchase.
